First off, just because she was chosen a lot in tournaments doesn’t mean the average person knows how to play her. She’s little chosen because, yes, to play Wattson you have to learn her and think.

You can see what happened: she didn’t get used less at top levels, but she’sbe chosen even less by everybody else.
